Lucky us – in 2016 we’re getting an extra 24 hours in the year. Nearly every four years, a day is added to the calendar as a corrective measure, because the Earth does not orbit around the sun in precisely 365 days.
Roman general Julius Caesar implemented the first leap day in his Julian Calendar, which he introduced in 45 BCE (Before Common Era). A leap day was added every four years. At the time, leap day was February 24, and February was the last month of the year. That calendar said any year divisible by four would be considered a leap year. However, adding a leap day every four years was too often and eventually, in 1582, Pope Gregory XIII introduced the Gregorian Calendar. This calendar, which we still use today, has a more precise formula for calculating leap years. There are three criteria that must be taken into account to identify leap years:
